HVAC reviews in Denton, Texas

I like to thank Dylan Tekell for being very professional and knowledgeable about his job. I believe he sets the standard of Cote's the best Heating & Air Conditioning company in North Texas. Thanks again Dylan for being so professional and a servant of God.

Dylan was great! He fixed our unit in under an hour and we didn’t have to stay the night in a hot house. I was extremely impressed with his customer service expertise. I’d choose Cotes again any day.

My wife and I just had our AC go out. We called Cote's and they came out the next day. Juan and his crew came by the following day, and overhauled the entire AC system. Very happy with our entire experience, highly recommend! Good honest company.

Our A/C went out Thursday (very hot) evening and my husband called Friday morning. We were not looking forward to trying to sleep in really hot conditions. Your service tech Houston made it to our home by 5 pm and by 6 our A/C was back on line. We are so grateful and pleased considering the 100+ temp the last few days. Professional, prompt, courteous and definitely on time. Thank you so much for getting us back to the cool zone. We even signed up for your yearly maintenance deal to keep our system running smooth. Thank you once again. The Littrells

The sales and install teams were very friendly, courteous, and efficient during the initial meeting and install of our new unit. The install team rank high as one of the nicest crews I have ever had in my home. There was damage to my home when someone from the install team accidentally stepped through my ceiling which resulted in a very large hole in my ceiling and damage in another area of the house. The install team assured us there would be a manager calling to schedule an onsite visit to evaluate the repairs. Six full days have passed and a manager has yet to call, come by or evaluate the damages. The office manager "has 15 years of experience" but lacks a sense of urgency in providing timely and professional communication and relies on automated texting software to communicate. No one from the company has addressed the damage to our home except the very apologetic install crews. If someone had addressed us immediately with care and concern regarding the damage, I would be more willing to leave a high review.

Cancelled last second. I even said if they couldn’t come out last minute I would find someone else and it wasn’t a problem. Wasted 2 hours when I could’ve had another company come out and service my house. Extremely upset. DO NOT USE!

In 2022, I hired Cote’s Mechanical to help resolve cooling issues in my home. The owner at the time, Cote Wyatt, told me that my A/C unit was a 4-ton system and too small for the house. Based on his recommendation, I paid $4,400 to install a ductless mini split on the second floor and re-zone my master bedroom.

I recently discovered that my existing A/C unit is actually a 5-ton system, which is properly sized. The real cause of the cooling issues was a piston that was never replaced when the evaporator coil was installed—an oversight on their part.

Because of this misdiagnosis, I now have a mini split system that was never necessary, is leaking freon, and negatively affects the appearance and resale value of my home. I reached out to Mr. Wyatt in good faith and gave him multiple chances to respond. He admitted via email that he owned the company until April 2025 but has not responded since July 2, despite a formal written request to resolve the issue.

I am now having to pursue action through the Texas Department of Licensing and Regulation.

I would caution anyone considering this company. What happened to me was not just an expensive mistake—it was a clear failure to diagnose and correct a basic issue, which led to unnecessary cost and damage.

UPDATE: I wanted to provide an update to my previous review regarding my experience with Cote’s Mechanical. After initially encountering issues with a misdiagnosed A/C system and an unnecessary mini split installation, I am pleased to report that the current management took responsibility and worked with me to reach a fair resolution.

The company promptly reimbursed me for the costs related to the unnecessary installation and the required repairs. Throughout the process, the new general manager, Brad Hehn, was professional, responsive, and committed to making things right.

I appreciate their willingness to correct the situation, and I feel confident recommending Cote’s Mechanical moving forward.

Zach Morgan came out to investigate a start up noise with the AC unit. He was friendly & knowledgeable and installed a soft start kit. AC start up is very quiet now, plus surge protection. Unrelated to the service call, he connected the thermostats to my Home app. Thank you Zach, job well done!

I needed Service on my A/C system and Cote's sent over Jacob M. who was quick, detailed and professional. He inspected the entire system until he found the actual problem and repaired. I appreciated the way he explained the problem in detail and was quick to get it resolved and the A/C was pumping cold again. Highly recommend Cote's and make sure you ask them to send Jacob!

We had the pleasure of working with Dylan for our AC service, and I couldn’t be more impressed. From the moment he arrived, he was professional, courteous, and respectful of our home. He took the time to carefully explain the issue with our unit in a way that was easy to understand, and he walked us through the options without ever making us feel pressured.

Dylan’s attention to detail and knowledge were clear right away. He worked efficiently, but never rushed, and made sure everything was running perfectly before he left. On top of that, he went above and beyond by checking a few extra things to ensure our system would stay in good shape long-term.

It’s rare to find someone who combines technical expertise with genuine kindness, but Dylan does both effortlessly. If you’re looking for someone you can trust with your AC needs, Dylan is absolutely the technician to ask for.

If I could give Zach and Cote's more than 5 stars I would. Zach was prompt, courteous and explained the issues in detail. He went above and beyond finding and fixing the issues I had. Cote's is the only place I will use for both maintenance and repair.

My tech was professional, thorough in his diagnostic and explained what needed to be fixed, after my AC was already up and running. Definitely was a trustworthy experience and as my tech modeled how to keep my AC and MiniSplit systems clean routinely, I will be gaining the benefit of their yearly membership. It’s great to have a dependable team so that if anything does come up, I know that it will be taken care of.

Cote’s was referred to me, and now I see why.
Jacob Morris exceeded my expectations!
His knowledge, professionalism and a thorough assessment of my unit was given with clear concise communication.
Jacob is definitely an asset for the Cote’s Heating & AC Co. !! Thank you Jacob!!

Dylan was our tech today. He was very friendly. Provided exceptional service and detail information. Very professional & respectful. Definitely 5 Star service! My Mom Donna R. and I very satisfied!!

My husband chose this company because it’s local. He signed up for their maintenance plan and had a good spring visit. Unfortunately, the tech who came out for the fall visit insisted that we needed to spend $7100 to replace 1 of the units’ coils. He noted that to my husband that he makes a lot of money on “leaky Lennox’s”, that we had mold throughout the system and advised that we buy UV lighting. There were other items that he recommended to include replacing the entire system (installed in 2016) for nearly $30k.
My husband wanted to get other quotes (with complete understanding that there were leaks with the unit). He had seen where the system had frozen up and was dripping into the drip pan. (This is our 5 home we have owned, first preowned home)
We received another quote from a kind man who doesn’t have as much overhead for $3100 for the coils replacement, yes we gave him our business and will continue to support the businessman who earns our trust with honesty and non sales pitchy attitude.
I felt that just because we live in a large home and drive newer cars doesn’t justify being taken advantage of.

Zach M. was fantastic! He arrived promptly within the time window that was communicated when the service was scheduled. He took time to explain different functions and issues we were experiencing with our A/C unit. Within a short time we began to feel cool air once again. He went out of his way to reset and configure my smart thermostat and then did a home walkthrough with his temperature reading laser tool. He shared several recommendations that we have added to our home rehab list and we signed up for the ongoing service from Cotes based on the amazing experience. Thanks Zach and Cote’s!

Cody has been out to our house several times since we started using Cote’s Air Conditioning Mechanical. We want to recognize his knowledge & outstanding service that he provides.
Cody is an asset to your company!

Raghbir was very prompt, thorough and quick. He really did a great job. Will definitely request him next time if we can.

Albert did an amazing job!! I thought my unit wasn’t working properly and he did an amazing job by looking at the unit and explaining and showing me some things on what to look at and where the heater furnace was located and recommended a duct cleaning!!

CADE was my tech that came to my house for my maintenance. He went above and beyond- at least in comparison what everybody else has done in the past. I felt comfortable with his recommendations, he left everything very clean, explained everything thoroughly and was an absolute professional. If I could give him 10 Stars I would but Google only allows five. He's the only person I want to come do my maintenance.

Nick was wonderful! Checked everything out for me and fixed the issue. Explained all options for me also for when I need to replace my unit.
